IUBMB Comments The enzyme is specific for glucosamine and has only a minor activity with D -glucose. Two unrelated enzymes with this activity have been described. One type was studied in the bacterium Vibrio cholerae , where it participates in a chitin degradation pathway. The other type has been described from actinobacteria, where it is involved in the incorporation of environmental glucosamine into antibiotic biosynthesis pathways. cf . EC 2.7.1.147 , ADP-specific glucose/glucosamine kinase.
The expected taxonomic range for this enzyme is: Bacteria, Eukaryota, Archaea
